Background of the invention

Scope of the invention

The present invention relates to a connector for connection to a charging seat and a charging seat assembly incorporating the connector.

Description of the state of the art

In the prior art, a copper wire is usually electrically connected to a terminal of a charging seat. To connect the copper wire to the charging terminal, a terminal is usually connected to one end of the copper wire and fixed to one end of the charging terminal with a bolt.
